Specification of Letters Patent.

Application filed September 20, 1907. Serial No. 393,844.

To all whom it may concern:

Be it known that I, THOMAS BUTTER- woR'i'H HARRISON, a subject of-the King of Great Britain, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented new and useful Improvements in Gas-Burners, of'which the following is. a specification.

This invention relates to gas burners and one of the principal objects of thevsame is to provide means for automatically regulating the flow of gas through the burner.

Another object of the invention is to provide a sliding aluminium valve disk which is adapted to be moved by the pressure of gas to regulate the flow of gas Athrough the burner. i

These and'other objects may be attained by means of the construction illustrated in the accompanying drawing, in which Figure 1 is a central vertical section through a gas burner made in accordance with my invention.. Fig. 2 is a plan view of the plug or fitting at the lower end of the Fig. 4 is a perspective view of the sliding valve disk, looking at-the under side.

4Referring to the drawing for a more specific description of my invention, the nu meral 1 designates the plug or fitting for the lower end of the burner, said fitting being interiorlyA screw threaded as at 2 to fit an ordinary gas su ply pipe, said fitting havin an annular bear 3 and the upper end of sai burner tube 5. The upper end of thef fitting series of perforations 6. l The threaded portion. 4 fits the threaded ortion 7 ofthe burner tube. A .wire sha t or spindle 8 is extends upward into a hollow tapering thimend of said burner tube, an upwardly pro- An aluminium valve disk 11 having a downwardly projecting peripheral :flange 12 is provided with a central aperture 13 said dis beingmounted upon the spindle 8 to slide freely thereon. An ordinary gas tip 14 is secured in the upper end of the burner tube 5.

The operation of' my invention may be 'briefly described as follows z-When the gas is turned on through the burner if the ressure is excessive, the aluminium disk Wi rise upon the spindle 8 to a position to regulate the flow of gas throu h the burner. Should the pressure be su would rise to the position shown in dotted lines in Fig. 1, then the full pressure of gas passes through the perforations 6, but permits only a slight low` to pass through between the top part of the valve disk 11 and the seat of said valve. i

From the foregoing it will be obvious that,

a burner made in accordance with my invention automatically regulates the flow of as, that the invention is simple in construction, can be readily attached to any gassupply pipe and is very efficient for the purpose.

Having thus described the invention, what is claimed as new, is

A gas burner comprising a tube, a hollow tapering thii'nble provided with a top secured, to saidburner tube an provided with an-open lower end, a fitting rovided with a perforated top secured in t e lower jecting spindle secured to said perforated top and extending into the openl 'lower' end of said thiinble, and an aluminium valve disk havin a downturned eripheral edge mounted to s ide upon said s aft or spindle. 1 4

In testimony whereof I affix my signature in presence of two witnesses. y
